ISA 80x50x8
IS — Angle Section
Angle sections (L shapes) are used for bracing, connections, lintels, and built-up members. Available in equal and unequal leg configurations.
The ISA 80x50x8 steel profile weighs 7.2 kg/m (4.85 lb/ft), has a depth of 80 mm (3.15 in), flange width 50 mm (1.97 in). Cross-sectional area: 976 mm². Moment of inertia Ix = 62.87 cm⁴, Iy = 19.05 cm⁴.
